Aerodynamics

It gives it the aerodynamic shape, it carries a share of the loads, it helps to carry torsional loads, it acts as fuel tanks and allows inspection and maintenance. Using the skin to carry part of the loads is called stressed skin. Almost all aircraft have their wing structure…

The X-15 was the brainchild of NASA (recently NACA), US Air Force, US Navy, and North American Aviation Inc. For nearly a decade (June 8, 1959 - October 24, 1968) the X-15 flew 199 times supplying countless reports of data for aerodynamics, high altitude (exit and reentry of atmosphere), hypersonic speeds, and physiological effects on pilot. During this time the X-15 set the altitude record of 354,200 feet and top speed record of Mach 6.7 (4,520 miles per hour). Because of the massive speeds…

Drag force is an aerodynamic force which acts parallel and opposite to the motion of the object when it moves through a fluid. It is caused by friction and differences in air pressure. There are many factors can affect the magnitude of drag force as with aircraft lift. The drag depends linearly on the shape and size of the object moving through the air. The object’s cross-sectional shape determines the form drag which is created by the pressure variation around the object and affects the…

What are aerodynamics? Does it have a history? How does an organism or object fly? What are some examples of aerodynamics? These three questions will be answered in this essay. The definition of aerodynamics and how it can be used or help in the world, the history of aerodynamics, the four forces of flight, and examples of objects or organisms that use aerodynamics will all be applied and valued in this essay. What does aerodynamics mean? Aerodynamics is a branch that is concerned with studying…

Fluid dynamics and Bernoulli's equation Moving fluids Fluid dynamics is the study of how fluids behave when they're in motion. This can get very complicated, so we'll focus on one simple case, but we should briefly mention the different categories of fluid flow. Fluids can flow steadily, or be turbulent. In steady flow, the fluid passing a given point maintains a steady velocity. For turbulent flow, the speed and or the direction of the flow varies. In steady flow, the motion can be represented…

Friction loss is defined as the pressure loss or head loss that usually occurs in pipeline fluid flow because of the viscosity effect near the surface of the pipe. When the fluid flows along the pipeline, it produces frictional resistance thus results in loss of energy or total head loss of the fluid. Therefore, experiment was conducted to verify the Darcy Weisbach equation by determining the pressure loss along a horizontal pipe. Figure A below shows the diagram of friction loss along a…

ORIFICE PLATE: Definition: An orifice plate is a device that is used for the measurement of flow rate for reducing pressure or for the restricting flow. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (either liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice. But as the fluid is forced to converge to pass through the hole, the velocity increases & the fluid pressure decreases. Orifice Plate…

Introduction To understand aircraft propulsion it is important to understand the term propulsion first. Propulsion is a means of producing force required for movement of object. The propulsion system has some source of mechanical power and some means of using this power to generate force such as wheels, propellers, legs, etc. Nobody can precisely tell the origin of mankind’s desire to fly as it is lost in the distant past. There are legends of people strapping birdlike wings and jumping of a…

Propulsion is a force that pushes forward or drives and object forward. This concept can be seen in action with the use of a balloon powered car; this car demonstrates a type of propulsion system in which it produces thrust and potential energy and uses the kinetic energy that it will gain from the movement to push the car forward. The thrust is obtained from the balloon which applies Newton’s third of motion that states, “for every action, there is an equal and opposite reaction.” Specifically,…
